The 3-phase induction motor is so designed that the rotor should have ______ under running conditions.

  • The 3-phase induction motor is so designed that the rotor should have low resistance under running conditions.
  • In general, the rotor of a 3-phase induction motor is designed to have a lower resistance under running conditions compared to its reactance.
  • A low rotor resistance allows for a higher rotor current and a higher torque production, while a high rotor reactance limits the rotor current and torque production.
  • The torque produced by the motor is proportional to the rotor current and the magnetic field interaction between the rotor and stator fields.
  • A low rotor resistance allows for a higher rotor current and a higher torque production, while a high rotor reactance limits the rotor current and torque production.
  • A lower rotor resistance is desirable in order to achieve higher torque output and better motor performance.
